摘要： Methods and apparatus for communicating information using a plurality of report dictionaries are described. A plurality of request dictionaries are implemented for a wireless terminal to use for multi-bit uplink transmission backlog request reports communicated via the dedicated control channel. Each dictionary defines a different bit mapping interpretation for a set of multi-bit uplink transmission backlog request reports, e.g. a 3 bit uplink request report and a 4 bit uplink request report. The plurality of request dictionaries includes a default dictionary and additional dictionaries. The implementation of a plurality of alternative request dictionaries expands the reporting possibilities allowing a wireless terminal to use a reporting format well-suited to its current needs. The default dictionary is mandated to be used under certain predefined conditions, e.g., upon entry into the active state. Rules for transitioning between different dictionaries and continuing to use a selected dictionary are described.

摘要： Methods and apparatus related to reporting transmission backlog information are described. A wireless communications device maintains and updates transmission backlog information corresponding to a plurality of different transmission request groups. Different request groups may correspond to different uplink traffic queues. For a request reporting opportunity, the communications device selects a request group from among the plurality of different transmission request groups as a function of: request group changes in backlog with respect to previously reported requests, the changes taking into consideration base station allocation of transmission resources; and request group priority information. A request report is generated conveying backlog information corresponding to the selected request group, and the generated report is transmitted over a wireless communications link.

摘要： Aspect of the present disclosure include A Mobile Ad Hoc Network (MANET) in which an intermediate relay node may engage in discreet packet-dropping practices for selfish (e.g., to conserve power) or other reasons. Each node in such a MANET has a dynamic reputation level known to all other nodes. Embodiments include improving the overall performance or robustness of such a MANET by adopting a routing strategy (e.g. routing protocol) which considers the reputation levels of intermediate relaying nodes in determining the best route from a source to a destination. Embodiments of the present disclosure also include a system for discovering a route between two nodes in a communication network. One or more nodes: (i) determine a reputation level of each neighboring node; (ii) sending a route discovery message that is addressed to the destination node to one neighboring node having a highest reputation level.

摘要： A wireless communications system supports wireless connections between base station sector attachment points and wireless terminals. Individual wireless connections correspond to one of a downlink-macrodiversity mode of operation and a downlink non-macrodiversity mode of operation. A wireless terminal has, for each of its current connections, a base station assigned dedicated control channel for communicating uplink control information reports. The uplink control information reports include downlink signal-to-noise ratio reports based on measured received pilot channel signals. If a connection corresponds to a macrodiversity mode of operation, a reporting format for the SNR report is used which reports (i) an SNR value and (ii) an indication as to whether or not the connection is considered a preferred connection by the wireless terminal. If a connection corresponds to a non-macrodiversity mode of operation, a reporting format for the SNR report is used which reports an SNR value.

摘要： An uplink dedicated control channel reporting structure includes a plurality of different bit size reports, e.g. 1 bit, 3 bit and 4 bit reports, for reporting a wireless terminal's backlog information of uplink traffic request group queues. Smaller bit size reports are transmitted more frequently than larger reports. A 1 bit request report indicates whether or not there are any MAC frames of information to be communicated in a set of two request group queues. A 3 bit request report indicates an amount of backlog information corresponding to a first set of request group queues and a second set of request group queues. A 4 bit request report indicates an amount of backlog information corresponding to a set of request group queues. The 4 bit request report is capable of reporting information on any of a plurality of uplink traffic channel request group queues being maintained by the wireless terminal.

摘要： Systems and methodologies are described that facilitate generating and/or analyzing downlink transmission units in OFDM TDD environments. Beacon signals may be selectively inserted within downlink transmission units; for example, the position of Beacon signals may vary from cell to cell. Further, the position may be a function of a characteristic of a cell (e.g., cell identifier) and/or an expected drift. Moreover, a Beacon signal may be interjected at a location in a downlink transmission unit so as to mitigate alignment with disparate Beacon signals in downlink transmission units associated with differing cells. Additionally, an identity of a cell providing downlink transmission units may be determined by analyzing a position of the Beacon signal within the downlink transmission units.

摘要： Systems and methodologies are described that facilitate utilizing different power control algorithms as a function of access terminal speed. For instance, instantaneous Channel Quality Indicator (CQI) reports can be inverted for slow moving access terminals while long-term geometry inversion (e.g., average CQI report inversion) can be utilized for quick moving access terminals. Speed of the access terminal can be estimated based upon time correlation of CQI values. Further, selection of implementing instantaneous CQI inversion or long-term geometry inversion can be based upon the estimated speed of the access terminal.

摘要： An adaptive incremental redundancy (i.e., Hybrid ARQ) method is described for retransmitting information in a communication channel of a wireless communication system. More specifically, code multiplexing is used within fixed length frames in order to change the number of codes, modulation, and coding on retransmissions to provide the desired redundancy for successful decoding. The operation of adaptive Hybrid ARQ in the code domain also provides finer granularity in which to efficiently transmitting redundancy. In one illustrative embodiment, a method for retransmitting information in a communication channel having a plurality of fixed length frames each divided into a plurality of time slots of equal duration includes the step of code multiplexing a retransmission of a previous transmission within one of the fixed length frames using one or more of a plurality of codes. The number of codes used for the retransmission is variable based on the condition of the communication channel.
